Santos opened the scoring in the first minute, only for Ji Soo-hwang to level just before the half-hour mark.

However, Santos added a second shortly after the hour before compatriot Roger and a late Kwon Chang-Hoon effort condemned the visitors to a first league defeat in seven matches.

That result saw Bluewings leapfrog Jeju United into third, with Park Kyung-hoon's side held 1-1 by Busan I'Park on Saturday.

Meanwhile, Incheon United moved off the bottom with only their second top-flight win of the campaign as they won 2-0 to put a further dent in Ulsan's top-six hopes.

Ulsan have faltered of late and now hold just a two-point cushion over Seoul after Jin Sung-wook and Choi Jong-hwan wrapped up victory for the strugglers.

Second-half goals from Sreten Sretenovic and Everton Santos ensured that Gyeongnam and Seoul shared the spoils 1-1, while Sangju Sangmu and Seongnam remain level on points after drawing by the same scoreline.

South Korea international Kim Tae-hwan opened the scoring after just six minutes at the Sangju Stadium before Baek Jong-hwan levelled just before the hour mark to earn the hosts a point.
